Hello,
A co-worker of mine needs a PERL style regular expression that can match
the numbers 500-1800 NON-inclusive. This is for a web application
(WebCT), and if you want to validate a field in the built-in quiz module,
you can only use a PCRE. This feature is generally used to allow students
to type in answers that are case-insenstive, or allow for slight
misspellings, but in this case we're trying to bend the regular expression
support to do a little math for us.
Anyway, I came up with the following:
(^[5-9][0-9]{2}|^[1][0-7][0-9]{2})
This seems to be working for 500-1799, but apparently we're supposed to
rule out 500 as well.
Any ideas?
Thanks for your time,
Dave M.
